“…Finally, Je et al experimentally evaluated the performance of Wi-Fi Direct in streaming applications with respect to RTT and the communication bandwidth [7]. More recently, a framework for constructing multihop networks based on Wi-Fi Direct has been proposed in [1,16], and a method to increase the communication bandwidth of Cellular-V2X (vehicle to X) networks with the aid of Wi-Fi Direct is proposed in [20]. However, to the best of our knowledge, there are no studies that attempt to realize live video streaming on MANET based on unstable communication links such as Wi-Fi Direct.…”

This paper proposes a method to realize a reliable live video streaming over mobile ad hoc networks (MANETs) consisting of several Wi-Fi Direct groups. The proposed method uses a multi-path routing with two disjoint routes connecting a source to several subscribers so that if the primary route temporally becomes unavailable, the source immediately switches to the secondary route, which is regarded as a new primary route, and starts the exploration of a new secondary route by invoking a variant of AODV protocol. The result of experiments with twelve Android tablets indicates that it could stably deliver a live video stream of QVGA quality to a subscribing node located at 200 m away from the source node, and quickly recovers from link failures in 100 ms which is significantly shorter than the original AODV.
